IMPROVEMENT IN BOTTLE-CAPPING MACHINES.

Specication forming part of Letters Patent No. 116,107, dated J une 20, 1871.

To all whom 'it may concern:

Be it known that I, WILLIAM H. SPERLING, of Washington, in` the county of Middlesex and State of New Jersey, have invented a new and useful Improvement in Bottle- Capping Machines; and'I do hereby declare that the following is a full, clear,A and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention consists in a machine for capping the mouthsl of bottles with tin-foi] or similar material, constructed and operating as hereinafter described.

The accompanying drawing represents a side elevation of the machine, partly in section, the table upon which it is placed and the treadle by which the jaws are opened being shown inA dotted. lines. i

Similar letters of reference indicate corresponding parts.

A is the fixed jaw on the teeth or bench B, in the end of which is a semicircular cavity made to lit one-half of the circumference of the neck of the bottle. If the neck of the bottle has grooves or beads thereon the cavity in the jaw is made to correspond therewith. G is the lever, forming a movable jaw, which is worked upon the fulcrum D on stands E on each side of the jaw A. In its end is a semicircular cavity, the same as that in the jaw A. The

Vthe bottle is represented by dotted lines. F

is a spring, the lower end of which is attached to some fixture, as the iloor or the table, and the upper end to the band Gr, which is attached to and operates on the upper jaw C.

In capping the bottle the foil cap is placed on the bottle, coveringits mouth and extend ing down onto the neck, as seen in the drawing. The pressure of the spring G is sufficient to compress the cap to the neck or nozzle, making it conform to the exact shape thereof in the shortest space of time. The jaw C is raised, so as to admit and release the bottle, by means of a foot-treadle, H, and connection I, as represented. In this manner the foil caps may be made to conform to the exact shape of the neck ofthe bottle in a most perfect and expeditious manner.

Having thus described my invention, I claiml
